Controller层的统一异常处理（@ControllerAd

要将自己的系统异常进行细分，具体是业务异常还是其他什么异常

@ControllerAdvice
public class ExceptionController {

    /**
     * 日志对象
     */
    private final Logger logger = LoggerFactory.getLogger(getClass());

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        binder.registerCustomEditor(Date.class, new DateEditor());
    }
    /**
     * 无授权异常处理
     * @return  授权异常
     */
    @ExceptionHandler({UnauthenticatedException.class})
    @ResponseStatus(HttpStatus.UNAUTHORIZED)
    @ResponseBody
    public Object unauthorizedException(Exception e) {
        logger.error("ExceptionHandler:"+e.getMessage(),e);
        return handleExcetion(e);
    }

    /**
     * 登录异常处理
     * @return 登录异常
     */
    @ExceptionHandler({ShiroException.class})
    @ResponseStatus(HttpStatus.NOT_ACCEPTABLE)
    @ResponseBody
    public Object shiroException(ShiroException e) {
        logger.error("ExceptionHandler:"+e.getMessage(),e);
        return handleExcetion(e);
    }
    /**  
     * 用于处理异常的  
     * @return 业务异常
     */  
    @ExceptionHandler({AdderBusinessException.class})
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ResponseBody
    public Object businessException(AdderBusinessException e) {
        logger.error("ExceptionHandler:"+e.getMessage(),e);
        return handleExcetion(e);
    }

    /**
     * 用于处理异常的
     * @return 无服务异常
     */
    @ExceptionHandler({NoHandlerFoundException.class})
    @ResponseStatus(HttpStatus.NOT_FOUND)
    @ResponseBody
    public Object notFoundException(NoHandlerFoundException e) {
        logger.error("ExceptionHandler:"+e.getMessage(),e);
        return handleExcetion(e);
    }
    /**
     * 用于处理异常的
     * @return 业务异常
     */
    @ExceptionHandler({HttpRequestMethodNotSupportedException.class})
    @ResponseStatus(HttpStatus.METHOD_NOT_ALLOWED)
    @ResponseBody
    public Object methodNotSupportException(HttpRequestMethodNotSupportedException e) {
        logger.error("ExceptionHandler:"+e.getMessage(),e);
        return handleExcetion(e);
    }

    /**
     * 用于处理异常的
     * @return  系统异常
     */
    @ExceptionHandler({RuntimeException.class,Exception.class})
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    @ResponseBody
    public Object systemException(Exception e) {
        logger.error("ExceptionHandler:"+e.getMessage(),e);
        return handleExcetion(e);
    }

    protected Map<String,Object> handleExcetion(Exception e){
        Map<String,Object> rs = new HashMap<>();
        rs.put("message",e.getMessage());
        rs.put("class",e.getClass().getName());
        return rs;
    }
}

使用@InitBinder，日期编辑器兼容日期,时间和日期时间三种类型

public class DateEditor extends PropertyEditorSupport {  
  


    private boolean allowEmpty = true;  
  
    /**
     * 构造方法
     */
    public DateEditor() {  
    }  

  

    /* (non-Javadoc)
     * @see java.beans.PropertyEditorSupport#setAsText(java.lang.String)
     */
    @Override  
    public void setAsText(String text) throws IllegalArgumentException {  
        if (this.allowEmpty && !StringUtils.hasText(text)) {  
            setValue(null);  
            return;
        }
        if(NumberUtils.isNumber(text)){
            setValue(new Date(Long.parseLong(text)));
        }else{
            setValue(null);
        }
    }

    public String getJavaInitializationString() {
        Date value = (Date) getValue();
        return value != null?value.getTime() + "L":"null";
    }
}
